Adjust speed deviation scaling to be more harsh on low end (#36554)

Browse Source 
This should buff raw speed plays like Ivaxa Violation, at the same time
undoing part of the buff on the lower end scores like Save Me NM
Moved part of the multiplier out of the Pow to be more intuitive (it
multiplies the 20 by Pow(difficulty/4), so it's more clear that it would
be equal to 1 on difficulty = 4)
The scaling itself was adjusted to be more similar to live (so
buffs/nerfs on 98% acc remains +- the same through the difficulty curve)
